2. Description of the Related Art Conventionally, as a key ring of this kind,
No. 63-169668 and No. 63-4128
No. 2 or JP-A-2-120480.

In Japanese Utility Model Laid-Open No. 63-169668, as shown in FIG. 9, a notch 7 having substantially the same shape as the key 5 is formed from the outer periphery of the card 6 toward the center, and both sides of the notch 7 are formed. 7a, 7a and both ends of the grip portion 5a of the key 5 are connected by pins 8, 8, and the key 5 is mounted so as to rotate in a direction perpendicular to the card surface.

Japanese Utility Model Laid-Open No. 63-41282 discloses a recess 1 in which a key 9 can be inserted into the surface of a card 10 as shown in FIG.
1 and a thin plate 13 is attached to the surface of the card 10 so as to cover the lower half of
Key 9 connected to the card 10 through the recess 11
And a thin plate 13. A through hole 12 for taking out a key is formed in a portion of the recess 11 corresponding to the key head. Also, Japanese Patent Laid-Open No. 2-1204
The card also serving as a key holder shown in No. 80 is a card in which a spare key formed of a thin plate having no thickness or groove provided in the original key is rotatably attached to a flat base material provided with a shallow holding recess. .

[0005]

In the above-mentioned conventional card, the one disclosed in Japanese Utility Model Laid-Open Publication No. 63-169668 requires that the side of the card and the side of the key be connected by pins, and the card is assembled. In addition to the difficulty of working, there is a problem that the strength of the connecting portion is not sufficient due to the fact that both sides of the notch are easily bent or expanded.
Also, in this card, since the key is attached with a pin so that it can rotate in the vertical direction with respect to the card surface, there is a risk that the key may inadvertently jump out of the notch of the card,
Care must be taken when carrying the card, and the card swings with respect to the key even during use, and it cannot be said that the card is always excellent in handleability.

In Japanese Utility Model Laid-Open Publication No. 63-41282, a recess is formed in a card, a through hole is formed at a predetermined position of the recess, and a thin plate is formed on the upper surface of the lower half of the card. The card must be attached and the key and the key must be connected by a connecting cable, so that the number of manufacturing and processing steps is large and the cost is increased. Further, in this card, since a thin plate is attached to the lower half portion of the upper surface of the card, the thickness of the card is increased, and the thickness is not constant, so that the card is not necessarily excellent in portability. .
Further, Japanese Unexamined Patent Application Publication No. HEI 2-120480 discloses that a key accommodating this key is formed thin by making the key itself a thin plate, but the key does not have a predetermined thickness. There is a problem in handleability, strength, durability and the like, and there is a problem that it can only be used as a spare key in an emergency. Also, in order to pull up the tip of the key housed in the holding recess in a rotatable state, the card that doubles as the key holder must be forced to bend downward with the card itself flexed downward. In such a case, it is difficult to perform the operation, and in some cases, the card may be broken.

[0007] It is an object of the present invention to solve the above-mentioned problems of the conventional card which also functions as a key ring.

[0008]

According to the present invention, a recess formed in a card made of a synthetic resin material having flexibility for accommodating the head of a key is formed, and a key portion is formed continuously with the recess. The key is rotatably attached to the recess with a pivotal support penetrating the head of the key.

[0009]

The recess formed in the surface of the card serves as a holding portion for a pivotal support for pivotally attaching the key to the card, and also serves as a storage portion for storing the attached key substantially flush with the surface of the card. . The through hole formed in the card functions as a finger hook when taking out the key, and also functions to hold the stored key in a non-rotatable manner.

Further, the card having flexibility is bent so that the key portion can be rotated and pulled out from the through hole, and the card portion pressed against the back surface of the key to prevent the key portion from being accidentally rotated. Act on.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a plan view showing an embodiment of the present invention, FIG. 2 is an enlarged sectional view taken along line XX, and FIG. 3 is an enlarged sectional view taken along line YY. As shown in the drawing, a key 1 is integrally attached to a card 2 which also functions as a key holder according to the present invention, and this key 1 is another general key for a vehicle or a spare key thereof. The tooth shape may be cut in the key part in accordance with the tooth shape of the original key in advance, or
The key portion 1a may have only a general outer shape so that the consumer can carry out secondary processing after reaching the hand and use it as a desired spare key. The key portion 1a
Is substantially equal to or slightly larger than the thickness of the card 2 described later.

The card 2 is made of a synthetic resin material having flexibility, and has a circular recess 2b in which a head 1b of the key 1 can be stored near one side of the surface. The recess 2b is formed with a through-hole 2a which substantially matches the contour of the key portion 1a.

The card 2 and the key 1 are rotatably connected to each other by using a pivot support described later.

FIG. 6 is an exploded perspective view of the above embodiment. As shown, the key 1 is placed on the card 2 such that its head 1b is located in the recess 2b of the card 2 and the key portion 1a is located in the through hole 2a. From one of the pivotal supports 3a to the head 1b of the key 1.
And the shaft hole 2c formed in the recess 2b of the card 2 is inserted and attached, and the other pivot support 3b fitted to the pivot support 3a is attached from the back of the card 2. Thereafter, the two pieces are attached to the card 2 by caulking them together.

In FIG. 6, reference numeral 1e denotes a pivot support 3a.
1d is a step formed on the back surface of the key 1 to make the head 1b side of the key 1 thinner, and 1c is a key hole engaging formed on the surface of the key 1a. Shows the groove of.

The key 1 attached to the card 2 in this manner rotates about the pivotal supports 3a and 3b connecting the two, and can be stored and carried in a card shape. It can be pulled out in a state protruding from.

Next, the use of the card having the above-mentioned structure which also functions as the key holder of the present invention will be described. Normally, the key 1 is located in the through hole 2a and the recess 2b of the card 2 as shown in FIGS. The card 2 is stored in a state substantially flush with the surface of the card 2. When the card 1 is used, the card 2 itself is slightly bent, the tip of the key 1 is lifted from the surface of the card 2, and then the side of the key 1 is pressed from either the left or right. , Pivotal support 3a,
It turns to either left or right around 3b. At this time, if the back surface of the key 1 is pushed upward by using the through hole 2a formed in the card 2, the above operation becomes easy to perform.

When the key 1 is rotated about the head 1b in this manner, the key portion 1a of the card 2 is moved as shown by a two-dot chain line in FIG. 1 or a solid line in FIG. Since it protrudes from the peripheral edge, the key portion 1a can be inserted into a keyhole (not shown) of an object requiring locking or unlocking in this state, and can be used. At this time, the key 1 bends the card 2 and rides around the recess 2a, so that the back surface of the key 1 and the surface of the card 2 are pressed against each other. The key 1 will be blocked and will be held in its pulled out position. When the thickness of the head 1b of the key 1 is made smaller than that of the key portion 1a and a step 1d is formed on the back surface of the connecting portion between the head 1b and the key portion 1a, as shown in FIG.
When 1 is pulled out to one side of the card 2, this step 1d
As shown in the cross-sectional view of FIG. 5, the card is locked to the side surface of the card 2, and careless rotation is more reliably prevented.
Therefore, the card 2 can be used like a holding portion of the key 1, and the operation becomes extremely easy. The step 1d may be formed with a slope on the surface.

In order to store the key 1 after use, in the case where the step 1d is provided on the back surface, the side of the key 1 may be pressed while slightly lifting the key 1a. When the card 2 rotates around the supports 3a and 3b and the position of the key portion 1a coincides with the through hole 2a, the card 2 returns to its original state by its own elastic restoring force, so that the key portion 1a is inserted into the through hole 2a. The fitting and storage are completed. In the case where the step 1d is not provided, or in the case where the step 1d has a slope, the key 1 can be rotated and stored in the same manner as described above simply by slightly pressing the side surface of the key 1.

The key 1 thus housed is
Does not arbitrarily rotate and jump out of the card 2 unless the card 2 is bent and the tip of the key 1 is pushed.

In the above description, a card accommodating one key is illustrated. However, as shown in FIG. 7, two storage locations for keys 1 are arranged in parallel, and for example, a key for a car and a door key for a front door are simultaneously stored. You may do it. At this time, FIG.
By staggering the storage directions of the keys 1 and 1 as shown in the figure, it is convenient to find out which key is the corresponding key, and the card surface area can be effectively used. Further, a large number of keys can be stored simultaneously.

As described above, the card serving as the key holder according to the present invention is convenient for carrying because the key can be stored in the form of a card. In addition, the key is hard to be lost. In addition to being able to print and display patterns, explanatory notes, and the like, it can also be configured as a magnetic card or IC card and used for various purposes such as various membership cards. At this time, as long as the flexibility of the card is not impaired and the rotation of the key is not hindered, a back plate or the like may be attached to the back surface of the card, and the back surface may be finished in a flat plate shape.

In this embodiment, an example is shown in which a dedicated key having a shaft hole through which a pivot is inserted is used as a key attached to the card. Is provided with a hole for inserting the holder in the head, so that an adapter of various shapes to be fitted in this hole is prepared in advance, and if the pivotal support is inserted through this adapter, the head Other keys with different shapes of holes and holes can be similarly attached to the card.

In the embodiment, the swivel fittings which can be fitted to each other are exemplified as the pivotal supports. However, the pivotal supports may be any as long as the keys can be rotatably attached to the card. After the shaft hole is inserted, the tip is crushed, so that the key can be attached to the card so that it can not be dropped off, or the key can be similarly attached to the card by screwing the tip. Various materials can be used as long as they have sufficient strength and wear resistance as a shaft, such as metal and synthetic resin.

The key shown has a step 1d formed between the key and the key to make the head thinner, and a groove 1c for engaging with the keyhole is provided on the surface thereof. A concave portion 1e into which the head of the pivoting tool fits is formed in the portion, but these steps, grooves, and concave portions are not necessarily required, and the shape of the key is limited to the illustrated embodiment. Not something.

[0027]

As described above, the card serving as the key holder of the present invention is manufactured extremely simply because the key is pivotally attached to the synthetic resin card having the recess and the through hole by using the pivotal support. It can be manufactured easily and at low cost.

The keys are stored in a single thin card almost similar to a cash card or a telephone card, so that the keys are convenient to carry and the keys are hard to be lost. Because it is held in the hole, there is no danger of accidentally turning and popping out, but when used, the key part is stably held in a state that it protrudes from one side of the card, so handling is easy It has many excellent effects that have not been seen before.
